Refractoriness to initial chemotherapy and relapse after remission are the main obstacles to curing T cell acute lymphoblastic leukemia (T-ALL). While tumor heterogeneity has been implicated in treatment failure, the cellular and genetic factors contributing to resistance and relapse remain unknown. Here we linked tumor subpopulations with clinical outcome, created an atlas of healthy pediatric hematopoiesis and applied single-cell multiomic analysis to a diverse cohort of 40 T-ALL cases.

Article Synopsis
  • - Low-grade gliomas (LGG) are brain tumors that initially respond well to treatment but often progress to treatment-resistant, high-grade gliomas, highlighting the need for better clinical trial access to improve patient outcomes.
  • - A study analyzed LGG clinical trials in the U.S. from 2010 to 2023, finding 14 trials involving 1,067 participants, but many were general and only a small percentage focused on specific mutations.
  • - The research revealed underrepresentation of certain demographics, particularly Black, African American, and Asian participants, and identified geographic gaps in trial sites, especially in the Rocky Mountain and Southeast regions.

CRISPR-Cas genome editing is transformative; however, there is no simple tool available for determining the optimal genome editing technology to create specific mutations for experimentation or to correct mutations as a curative therapy for specific diseases. We developed editABLE, an online resource (editable-app.stanford.

Incivility is a growing concern for researchers and practitioners alike, yet we know little about how the team context is related to the way that employees respond to it. In this study, we examined the role of team mindfulness and its direct and buffering effects on individual-level promotion- and prevention-focused emotional coping. We also examined how these forms of coping were related to individual work engagement.

Purpose: Cohort building is a powerful foundation for improving clinical care, performing biomedical research, recruiting for clinical trials, and many other applications. We set out to build a cohort of all monogenic patients with a definitive causal gene diagnosis in a 3-million patient hospital system.

Methods: We define a subset (4461) of OMIM diseases that have at least 1 known monogenic causal gene.

Unlabelled: Forkhead box R2 (FOXR2) is a forkhead transcription factor located on the X chromosome whose expression is normally restricted to the testis. In this study, we performed a pan-cancer analysis of FOXR2 activation across more than 10,000 adult and pediatric cancer samples and found FOXR2 to be aberrantly upregulated in 70% of all cancer types and 8% of all individual tumors. The majority of tumors (78%) aberrantly expressed FOXR2 through a previously undescribed epigenetic mechanism that involves hypomethylation of a novel promoter, which was functionally validated as necessary for FOXR2 expression and proliferation in FOXR2-expressing cancer cells.

Previous observational work revealed that transient populations in a sustainable building disposed of waste more accurately when compared to patrons in a non-sustainable building. The current study uses an experimental design to replicate this observed effect and to investigate whether or not the built environment influences motivational factors to impact behavior. We find support that a building designed and built to communicate an atmosphere of sustainability can influence waste disposal behavior.

Response time (RT) is facilitated when a target appears at a cued (valid) location versus an uncued (invalid) location. Interestingly, this valid-versus-invalid RT difference increases as the percentage of valid trials increases. In the present study, we investigated the mechanism responsible for this proportion valid cueing effect (PVE).

Recent research has begun to explore not just the spatial distribution of eye fixations but also the temporal dynamics of how we look at the world. In this investigation, we assess how scene characteristics contribute to these fixation dynamics. In a free-viewing task, participants viewed three scene types: fractal, landscape, and social scenes.

Recent studies have found that participants consistently look less at social stimuli in live situations than expected from conventional laboratory experiments, raising questions as to the cause for this discrepancy and concerns about the validity of typical studies. We tested the possibility that it is the consequences of a potential social interaction that dictates one's looking behaviour. By placing participants in a situation where the social consequences of interacting are congruent with social norms (sharing a meal), we find an increased preference for participants to look at each other.

Current theory suggests that interpersonal synchrony is an important social behavior in that it not only serves as a form of "social glue," but it also arises automatically in a social context. Theorists suggest potential mechanisms for interpersonal synchrony, ranging from a "low-level" social-perceptual system account to a "high-level" social-motivational explanation. Past studies that suggest synchrony can be influenced by social factors do not discriminate between these accounts.

In order to develop a more sustainable society, the wider public will need to increase engagement in pro-environmental behaviors. Psychological research on pro-environmental behaviors has thus far focused on identifying individual factors that promote such behavior, designing interventions based on these factors, and evaluating these interventions. Contextual factors that may also influence behavior at an aggregate level have been largely ignored.
